For the big firms, very quickly - usually within a day or two. For the medium / smaller firms, it varies, but usually within two weeks I would say. Obviously these are just general timeframes, so please don't slam me with your personal exception when you got the call back 3 months later. The big firms are the most predictable - if you haven't heard anything within a couple of days, expect a nice little form letter in the mail.

I think pretty much all of my callback offers came within a few days of the interview, and the offers I received after my callbacks were within a week.

If the callback interview took place in the beginning of August (extremely early in the game), would the offers be made within a week as well or would they want to wait until they're done interviewing other applicants in job fairs and OCI?

I think this again depends on the firm size. If the office you interviewed at is hiring 50 summers, then they'll know right away no matter what the date is whether or not they want you - and they'll let you know too. If the office is hiring 2 or 3 summers, they probably will want to do more callbacks before making decisions on anybody.

This makes sense, especially if you have a callback before schools really dig into their OCI schedule. If the firm only has 2-3 spots to offer and is screening people at a lot of elite schools, it doesn't make sense to fill up all the positions before finishing OCI.
